Flutter 音频插件无法处理我的音乐链接

Question

希望有人正面临我的问题或可以提供解决方案。我使用 firebase 来保存和播放我的音乐。来自我的数据库项目的以下流链接不适用于 AudioManager ( https://pub.dev/packages/audio_manager ) 或 audioplayers 插件 ( https://pub.dev/packages/audioplayers )，我没有找到任何其他插件它以正确的方式工作的地方。老实说，让它与 AudioManager 插件一起工作会很棒。我还尝试在两个插件提供程序项目中提出问题，但目前没有任何成功。

我面临的问题： 功能停止功能无法识别停止。上一个和下一个以及 PlayPause 仅适用于延迟。在提供的示例中，我使用 AudioManager 插件。

在提供的示例中，我们有一个水平列表，当您按下右上角的按钮时，我试图停止播放音乐。使用流媒体链接无法识别任何内容。它忽略停止歌曲。下一首歌曲也有轻微的延迟。

如果您将音频链接更改为带有文件结尾的链接，则停止播放歌曲的效果非常好，延迟也更少。在我的情况下更重要的是在没有文件结尾的情况下获取链接源！

var audioFiles = [
    "https://docs.google.com/uc?export=open&id=1SaJWqfQuHnFtL7uqrzfYG31hzOnqDM3r",
    "https://docs.google.com/uc?export=open&id=1FZkFMjQyWguAl0RMAsYDEZ07c_Qf7gjz",
    "https://docs.google.com/uc?export=open&id=1GqrwQ3eRuiil0p-Na_R1tMAvggp9YrbH",
  ];

如果您使用文件类型结尾的链接，如下例所示，一切正常且没有延迟：

var audioFiles = [
    "https://www.soundhelix.com/examples/mp3/SoundHelix-Song-1.mp3",
    "https://www.soundhelix.com/examples/mp3/SoundHelix-Song-2.mp3",
    "https://www.soundhelix.com/examples/mp3/SoundHelix-Song-3.mp3"
  ];
